I have a suggestion that will give your theory a little more factual 'weight'...

Your calculations should factor in the progressive spring rate of every aftermarket lowering spring on the market.

The current crop of lowering spring for the M3 will all have different progressive spring rates, so they will all behave a little different with the OE shocks and struts.

From my perspective, Dinan and Eibach got it right...and everyone else got it wrong.
Correct me if I am wrong, but doesn't the Eibach's spring rate derive very closely to the AC Schnitzer spec? As I understand it, Eibach produces the springs for ACS to their specs, and the Eibach branded ones are very close in spec.?
